SRP recommends hiring a licensed electrician to install your charging station. When consulting with the electrician, be sure to ask the following:

Do I need to upgrade my electrical panel?

Is ventilation required?

What is the charging level?

How much does installation cost?

When will it be completed?

Will they submit all required permits and oversee inspections if required by the city?
NOTE: permitting and inspection requirements vary by city. Check with your local municipality for more information.

Types of at-home EV charging stations

Pure battery electric vehicles and faster, higher-voltage charging methods may require a home electrical panel upgrade in addition to a dedicated 240-volt circuit.

Level 1 (120 volts)

It uses the standard 120-volt outlet that typically won't require you to make modifications to your electric panels or home wiring. Confirm that your home's electrical panel is at least 15 or 20-amp, single pole by consulting with a licensed electrician.

Most plug-in hybrid electric vehicles take four to six hours to fully charge.

A battery electric vehicle takes 12 to 24 hours to fully charge.

Level 2 (240 volts)

It increases the charge power two to four times and decreases the typical full charge time for a battery electric vehicle to four to eight hours.

It will likely require a new dedicated circuit from the electric panel to a wall location near the EV parking spot.

Consult with a licensed electrician to verify that your home has a two-pole 30 to 50-amp electrical circuit breaker panel.

DC fast charging (400 volts)

It is the fastest charging method available.

Some vehicles can charge in as little as 15 minutes, depending on the battery type.
